FRANK HOFFNER, OF NAN'IICOKE, PENNSYLVANIA.

SPINNING M'ACHINE.

Application filed April 17, 1924. Serial No. 707,213.

To all whom it may concern:

Be it known that I, FRANK Horrnnn, a citizen of the United States, residing at Nanticoke, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Spinning Machine, of which the following is a specification.

The device forming the subject matter of this application is a spinning machine, and one object of the invention is to provide novel means whereby motion may be transmitted from a central motor-driven shaft to the lower spools without resorting to belts, gears and the like. Another object of the invention is to provide novel means for rotating the upper spools and to provide novel means for oscillating the annular roving guide. Another object of the invention is to simplfy, generally, machines of the kind under consideration, and to afford positive drives throughout.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

WVit-h the above and other objects in view, which will appear as the description proc-eeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within. the scope of what is claimed, changes in the precise embodiment of the invention shown, can be made, without departing fror the spirit of the invention.

In the accompanying drawings Figure 1 shows in vertical section, a device constructed in accordance with the in vention, parts being broken away, and parts appearing in section; "Figure 2 is a top plan; Figure 3 is a cross-section on the line 33 of Figure 1; Figure & is a sectional detail, showing one of the spindles raised, so that it will not rotate; Figure 5 is a per spective view showing the means whereby any spindle may be rendered inactive; Figure 6 is a fragmental side elevation, diagrammatic in nature, parts-being omitted; Figure 7 is a sectional View wherein one of the driving mechanisms appears in elevation; Figure 8 is a perspective view showing a portion of the roving guide; Figure 9 is a fragment-a1 detail view disclosing the means whereby the bearing rings for the spindles are supported.

In carrying out the invention, there is provided an upright frame 1 including a base 2 comprising a lower ring 3 and spokes 4. Standards 5 are erected on the ring 3 and are inwardly offset as at 6, the inwardly offset portions 6 of the standards carrying depending hangers 7 supporting a lower bearing ring 8 and an upper bearing ring 80.

he numeral 9 designates an intermediate member comprising an annular part 10 and spokes 11, the intermediate member being supported on the standards 5. The spokes 11 of the intermediate member 9 carry upstanding brackets 12 whereunto an upper member let, in the formof a ring, is secured. Bearings 15 and hangers 16 are mounted on the annular part 10 of the intermediate member 9. Flanged wheels 17 are located outwardly of the annular part 10 of the intermediate member 9 and are journaled on the bearings 15 for rotation about horizontal axes. An annular roving guide 18 is supported on the wheels 17 for oscillation. The roving guide 18 has forks 19, through which the material passes. The means for imparting oscillation to the roving guide 18 will be described hereinafter. A fixed annular guide 20 is located below the oscillatory roving guide 18 and is equipped with outstanding eyes 21, through which the ma terial passes.

The spools 22 on which the material is received are journaled loosely on shafts 22 having their ends detachably held in spring grips 24 mounted on the upper member 1d of the frame. The spools 22 are in frictional contact with the drive rollers 25, held on the members of a continuous annular shaft 26, the members of the said shaft being connected by universal joints 27, and being journaled in bearin s 28 mounted on the upper member 14 and located therebelow.

The numeral 29 designates, generally, an outer rotatable member disposed adjacent to the bottom of the frame 1, as shown in Figure 1, the rotatable member 29 comprising a hub 30 journaled in the base 2 of the frame 1, centrally of the base, spokes 31 radiating from the hub 30 and carrying upstanding arms. 32 on which is mounted a rim 33 having a downwardly and inwardly ext-ending flange 34 which is cone-shaped. The hub 30 of the outer rotatable member 29 is secured to the shaft 35 of an electrical motor 36 mounted on a bracket 37 carried by one of the spokes 11 of the intermediate member 9 of the frame. The shaft is located within a tubular shaft 38 driven by and constituting part of the electric motor 36, the shafts 35 and 38 being driven in opposite directions. The construction of the motor 36 is not shown in detail, since electric motors, capable of operating as described, are known in the art (see for instance U. S. Patent 87 5,484), and because I am aware of the fact that a specific form of electric motor cannot be claimed in the same application with av spinning machine. The lower end of the tubular shaft 38 is secured to the hub 39 of an inner rotatable member 40 comprising spokes 41 carrying a rim 42 having a downwardly and outwardly inclined flange 43 which forms an inverted cone, the flange 43 of the inner rotatable member 40 being adapted to cooperate with the flange 34 of the outer rotatable member 29, in a way and for a purpose which will be made manifest hereinafter.

The tubular shaft 38 carries a worm 44 coacting with a worm-wheel 45 on a shaft 46 journaled in bearings 47 on the member 9. At its inner end, the-shaft 46 is provided with a crank 48 pivoted to the inner end of a pitman 49, the outer end of the pitman being pivoted to a bell crank lever 50, fulcrumed at 51 on the annular part 10 of the intermediate member 9, the outer end of the bell crank lever being pivoted at 52, as in Figure 2, to the annular roving guide 18. Figure 7 shows that there is a worm 53 at the outer end of the shaft 46, the worm meshing with a worm-wheel 54 (Figures 7 and 2) secured to one of the members of the circumferential shaft 26 which carries the drive rollers: 25.

Spindles 55 are mounted in the bearing rings 80 and 8, for rotation, and for vertical sliding movement. The bearing ring 80 has cam bosses 56 adapted to cooperate with the cams 57 on levers 58, the spin dles 55 passing through the cam bosses 56 and the cam 57. Spools 59 are friotionally held on the upper ends of the spindles 55 and rest on the inner ends of the levers 58. Conical drive wheels 60 are secured to the spindles 59 and, when the machine is in operation, are engaged with the conical flange 34 on the rim 33 of the outer rotatable member 29 and with the flange 43 on the rim 42 of the inner rotatable member 40. The material 61 on the spools 59 extend upwardly through the eyes 21 on the fixed guide 20, and through the parts 19 of the oscillatory roving guide ,18 to the spools 22 at the top of the machine.

Before describing the operation of the device it may be observed that the base 2 of the frame 1 has depending bearings 62 whereon flanged wheels 63 are carried, the wheels being supported by an annular track 64, the construction being such that the entire frame 1 may be rotated about a vertical axis, to permit any desired portion of the machine to be brought into convenient reach of an operator, without rendering it necessary for the operator to walk around the machine.

In practical operation, the motor 36 rotates the shafts 38 and 35 in opposite directions, the rotatable members 40 and 29 being operated in opposite directions, the flange 43 of the rotatable member: 40 and the flange 34 of the rotatable member 29 cooperating with the conical drive wheels 60 to rotate the spindles 55 and the spools 59, the spindles 55 turning in the bearingrings 8 and 80. When the operator wishes to stop the rotation of any one of the spools 55, the corresponding lever 58 may be swung on the spindle whereupon the cam boss 56' will cooperate with the cam 57 and serve (Figure 4) to raise the spindle 55 and the conical wheel 60 until the wheel 60 (Figure 4) is out of engagement with the driving flange 34 of the rotatable member 29 and. out of engagement with the driving flange 43 'o the rotatable member 40.

)Vhen the spools 59 are rotated, as aforesaid, the material on the spools is twisted and spun as it proceeds upwardly to be wound on the upper spools 22. The upper spools are rotated by a train of elements comprising the drive rollers 25, the shaft 26, the worm wheel 54, the worm 53, the shaft 46, the worm wheel 45, the worm 44, the shaft 38, and the motor 36. In order that the material 61 may be led fairly and evenly on the spools 22, as shown in Figure 6, it is necessary that oscillatory movement be imparted to the roving guide 18. The means for imparting oscillatory movement to the roving guide 18 embodies (Figure '2) the bell crank lever 50, the pitman 49 (Figure 1), the crank 48, the shaft 46, the worm wheel 45, the worm 44, the shaft 38 and the motor 36.
